For each column we can see that there is a triangle that never “moves” (red circle) and that's our reference point and it follows the clockwise pattern . So we can expect that in the third column there will be a plain triangle at the upper left corner.
The rest is finding the ...

'B' is the correct answer.
I took the test 3 times in a row giving the exact same answers for problem 1 to 15 (14 correct + 1 wrong) and then gave the answer A, B and D on problem 31 for in each of the tests. A and D gives 88 iq, B gives 92 iq -> B is correct.
